Ensure the out value 'uc' in get_ucall() is properly reporting
UCALL_NONE if the call fails. The return value will be correctly
reported, however, the out parameter 'uc' will not be. Clear the struct
to ensure the correct value is being reported in the out parameter.

On s390x, we can neither exit via PIO nor MMIO, but have to use an
instruction like DIAGNOSE. Now that ucall() is implemented, we can
use it in the sync_reg_test on s390x, too.
